24 * This code unmangles RX packets. RX is the mutant form of RPC that AFS
25 * uses to communicate between clients and servers.
26 *
27 * In this code, I mainly concern myself with decoding the AFS calls, not
28 * with the guts of RX, per se.
29 *
30 * Bah. If I never look at rx_packet.h again, it will be too soon.
